When we all had a good stare at Marvin Humes having a heavy night out in Las Vegas on Tuesday, we all sort of assumed that was his stag do. But don’t be fooled by the matching t-shirts and naughty expressions – that was merely the warm up act.

It turns out that Marvin’s stag do is a whopping eight days long – at we’re still very much at the beginning.

The second stage of the boys’ wild trip to Vegas involved the stag being handcuffed to a dwarf called 5 Cent (we don’t think that’s his real name) during a night out in the party town.

Marvin was apparently told that he would be 5 Cent’s “b***h” all day, with the singer being instructed to wear a t-shirt that made him look like a lady in a bikini.

To be honest, we prefer it to most of Marvin’s low v-necks.

JLS bandmates Aston, JB and Oritsé claimed to be behind the cunning plan to strap Marvin to a dwarf all night (try not to think about toilet stops), but we’ve got a feeling this one may have been Rochelle’s idea.

If we were waving our fiancé off to Vegas – a city full of booze, strippers and wedding chapels – we’d take some fairly radical measures to prevent the night from turning into a scenario resembling The Hangover.

When one of her followers tweeted Rochelle with the saying 'What happens in Vegas, stays in Vegas', The Saturday replied: 'I'm sure his new pal is nice but he can stay there ha.'

We don't think that's what the saying is really about, but it's nice to see that Rochelle has an optimistic frame of mind.

But here’s to hoping she has some more tricks up her sleeve – the snap she tweeted this morning of herself in bed with Marvin is lovely – but she’ll need to come up with something a bit stronger than that. There’s six days left of the stag do, so who knows what else JLS have in store for Marvin?
